Abstract

The experience of supporting roof with bolts is mainly based on practical approach – hi and miss method. The theory of such support is descriptive than mathematical. Taking into account the complexity of mining – geological and mining technical conditions of underground mining it’s quite difficult to mathematically describe the destruction of entries roofs supported by bolts. Nevertheless even the quality identification of the factors causing roofs fall can give grounds to make plan of bracing and safety increase.
